Is the gold plating real gold?

It is a gold-colored plating over a base metal, not solid gold or gold fill. Expect the finish to dull or rub off at the clasp and pendant edges with frequent wear.

Will the crystal match my birthstone?

The colors are named loosely, so treat them as close matches rather than exact birthstone shades. Dark blue, green, red and clear cover the common months.

Can I wear it every day?

Short term, yes. Keep it away from perfume, sweat and water, and take it off before showering or swimming, since plating and glue-set stones degrade faster with moisture.

What chain does it come on?

It comes on a thin O-chain with a lobster or spring clasp. The listing does not state the length, so check the pendant drop before buying if you want a specific fit.

Is it a good gift for a baptism or confirmation?

It works as a keepsake-style gift because of the cross and the color choice. If the recipient expects fine jewelry, a solid gold or sterling cross is the better pick.
